Build Toolchain
Designs and maintains build tooling — bundlers (Vite, Webpack, Rollup, esbuild, Parcel, tsup), package managers (npm, pnpm, yarn, Pipenv, Poetry, uv), lockfile hygiene, pre-commit hooks, runtime pinning, build cache, module resolution, monorepo workspaces, reproducibility. Audits for non-deterministic builds, lockfile drift, mixed package managers, unpinned runtimes, broken caches, and hooks that mutate without staging. Use when adding a bundler, switching package managers, debugging slow or non-reproducible builds, configuring pre-commit, or laying out a monorepo. Triggers on "build", "bundler", "vite", "webpack", "rollup", "esbuild", "parcel", "tsup", "swc", "babel", "npm", "pnpm", "yarn", "pipenv", "poetry", "uv", "pip-tools", "lockfile", "pre-commit", "husky", "lefthook", "build cache", "slow build", "hmr", "tree shaking", "code splitting", "monorepo", "workspace", "turborepo", "nx", "reproducible build", ".nvmrc", ".python-version", "engines field", "build toolchain".
